PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent No. 635,831, dated October31, 1899.

- Application filed August 16, 1898. $erial No. 688,708. (No model.)

To all whom it may concern:

Be it known that 1, PULASKI S. WISE, a citizen of the United States,residing at St. Charles, in the countyof Madison and State of Iowa, haveinvented a new and useful Printing-Press, of which the following is aspecification.

The invention relates to improvements in printing-presses.

The object of the present invention is to improve the construction ofthat class of printing-presses employing a reciprocating typebed and animpression-cylinder, more especially the manner of mounting theimpressioncylinder, whereby it may be readily raised during the returnmovement of the type-bed to prevent the blanket or other covering of thecylinder from receiving any ink of the type.

A further object of the invention is to improve the construction of thefeeding mech anism and to provide a simple and comparatively inexpensivedevice whereby the paper will be automatically carried forward at theproper time to receive an impression.

The invention consists in the construction and novel combination andarrangement of parts, as hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of a printing-pressprovided with my improvements, the feed-table being removed to show thefeeding mechanism more clearly. Fig. 2 is a longitudinal sectional view,the upper or oscillating feed-roll being elevated. Fig. 3 is a similarview, the oscillating feedrolls being depressed for engaging a sheet ofpaper. Fig. 4 is a transverse sectional view. Fig. 5 is a detail view ofone of the standards. Fig. 6 is a detail perspective view of one of theeccentric bearings. Fig. 7 is a detail view illustrating the manner ofmounting the rockshaft. Fig. 8 is a detail view illustrating the mannerof adjusting the impression-cylinder.

Like numerals of reference designate corresponding parts in all thefigures of the drawings. v

1 designates a reciprocating type-bed carriage mounted in suitable waysof a framework 2 and arranged to reciprocate beneath animpression-cylinder 3, and the shaft of the be readily grasped by theoperator.

impression-cylinder carries a cogwvheel 4:, which meshes with the teethof a rack-bar 5 on the type-bed carriage, whereby the impression-cylinder will be alternately reversely rotated as the type-bed carriage isreciprocated. The journals of the impression-cylinder, formed by theshaft 6, are supported by vertical standards 7, having threaded shanks 8engaging suitable threaded openings of the framework. The upper portionsof the standards are rectangular and have circular open ings 9, in whichare arranged eccentric bearings 11, consisting of bars or shanks andannular enlargements or hubs arranged on the inner faces of the shanksor bars and pro vided with eccentric openings 13, which are adapted tobe raised and lowered to elevate and depress the cylinder when theshanks or bars are oscillated. The shanks or bars are connected byatransverse top bar 12, whereby they are adapted to be oscillated inunison.

In order to enable the bearings to be oscil lated, a handle 14 issecured to one end of the transverse connecting-bar 12 and arranged toThe bearings 11 are oscillated to raise the impression-cylinder and holdit. elevated during the backward reciprocation of the type-bed carriagein order to prevent any ink from the type from getting on the blanket1.5 or other coveringof the impression-cylinder. One end of the shaft 6is extended and is provided with an operating crank-handle 16, arrangedadjacent to the handle 14.

The paper is carried beneath the impression-cylinder on endless tapes17, passing around guide-pulleys 18, as clearly shown in Figs. 2 and 3of the accompanying drawings, in which the pulleys 18 are considerablyexaggerated in proportion to the cylinder for the sake of clearness, andthe said pulleys 18, which are located at opposite sides of thecylinder, are mounted on transverse shafts 19, which are journaled insuitable bearings. The endless tapes extend from one end of a feed-tableupon which the paper is placed,

them to feed the paper positively. The feedrollers are carried bylongitudinal arms 21 of a transverse rock-shaft 22, which has its endsjournaled in suitable bearings, and the rockshaft, which is preferablysquared or of other polygonal shape, has the arms 21 adjustably securedto it by means of set-screws 23. The inner ends of the arms 21 areprovided with loops or sleeves 24, conforming to the configuration ofthe rock-shaft and having threaded perforations for the reception of thesetscrews which engage the shaft.

A depending lever 25 is loosely mounted on one end of the rock-shaftadjacent to one side of the type-bed carriage, and it is adapted tobeengaged by an oppositely-beveled lug 26 of the same, whereby when thecarriage starts forward the rock-shaft will be rotated to cause thefeed-rollers to engage the paper, and thus cause it to be carriedforward by the tapes, causing the feeding of the paper to be positive,reliable, automatic, and properly timed. The lever 25 is loosely mountedon the rockshaft in order to permit the oppositely-beveled lug 26 topass it on the return movement of the carriage without affecting theposition of the rock-shaft, and the said lever 25, which is fulcrumednear its upper end 27, has the latter projecting above the shaft andarranged to engage a stop 27 on the same. The stop 27 consists of a lugor projection extending laterally from the outer face of a disk or plate28, which is keyed or otherwise s'ecuredto the rock-shaft. The forwardmovement of the beveled lug 26 of the type-bed carriage carries theupper end of the lever into engagement with the stop of the rock-shaftand produces a partial rotation of the latter, the feedrollers beingheld in their depressed position until the paper passes beneath theimpression-cylinder by means of the lug 26, which is of sufficientlength to produce this result. After the lug leaves the lower end of thelever the latter resumes its normal vertical position, and thefeed-rollers are elevated by a suitable spring. The return movement ofthe carriage swings the upper end of the lever 25 away from the stop ofthe rock-shaft.

In order to enable the paper to be properly positioned with relation tothe feed-rollers, a pair of oppositely-disposed guide-pins 29 areemployed, and these pins, which are connected with the arms of therock-shaft by curved shanks or bars 30, are automatically brought intooperative position when the feed rollers are raised. The curved shanksor bars 30, which are secured at their upper ends to the arms 21, extendoutward and downward therefrom, passing inward beneath the upper flightsof the endless tapes to arrange the guide-pins at the inner edges of thesame. After the paper receives an impression of the type it passesupward at the opposite side of the impression-roll and is carried by thefingers 31 to a suitable table in the usual manner. The invention hasthe following advantages: The eccentric bearings of theimpression-cylinder enable the latter to be lifted clear of the type toprevent ink from getting on the blanket, and the feed mechanism,which ispositive, reliable, and automatic in its operation, enables the paper tobe rapidly and acou rately fed and greatly increases the prin tingcapacity of the press. The guide-pins, which limit the forward movementof the paper in placing the same in position for feeding the press, areautomatically brought into operative position and are similarly carriedout of the path of the paper before the feeding movement begins.

Changes in the form, proportion, and minor details of construction maybe resorted to without departing from the spirit or sacrificing any ofthe advantages of this invention.
